These components are present in suitable proportions, as described in more detail hereinbelow, so as to achieve the desired results in terms of physical properties (i.e., strength, hardness, etc.).
  • compositions of the invention form a rigid polymeric material upon radiation curing.
  • compositions include the following components in the stated weight percentages:
  • Lubricant (Optional) 0-0.25%

  • R is an aromatic hydrocarbon (for rigid compositions) or an aliphatic hydrocarbon (for flexible compositions), or a combination aliphatic/aromatic to obtain intermediate properties.
  • R 2 and R 3 are aliphatic hydrocarbons of relatively short chain length (C 3 . 5 ) when rigidity is desired, and of relatively longer chain length (C 15 - 20 ) when maximum flexibility is desired.
  • the R, and R $ components in the diisocyanate units are preferably aliphatic hydrocarbons for flexible polymers and aromatic hydrocarbons for rigid polymers.
  • the I ⁇ and R 7 components are methacrylate or acrylate ester groups which provide the ethylenic unsaturation necessary for the resins to be polymerized, so as to form the desired molded shapes upon application of radiant energy.
  • the acrylic-functional resins of the type described above are combined with diluent monomers and other additives, including photosensitizers, synergistic reducing agents, lubricants, thickeners, reinforcing fillers and pigments to achieve the desired molding composition.

  • a photosensitizer or photoinitiator is used if the material is to be cured by radiant energy of wavelengths within the ultraviolet or visible regions of the spectrum.

  • Reinforcing fillers which are also optional, may be added to maximize the strength properties of the resulting material, particularly where rigidity is desired.
  • Such fillers are generally utilized in larger proportions when the resulting materials are to be used as "solid” forms or shapes, as opposed to hollow forms or shells with relatively thin walls.
  • suitable pigments of the soluble, insoluble and "Lake "-type are used to achieve the desired color in the final product, except in applications where the final product is to be colorless or "clear. " It is believed that the sub-micron sized thickeners serve to prevent the sedimentation of the pigments and reinforcing fillers.

  • composition is curable by exposure to visible light radiation.
  • microwave radiation curing can be utilized.
  • Contemplated surface treatment is silanation (treatment with organofunctional silane) to convert the surface of the particles from hydrophilic to hydrophobic; this enables better wetting with the resin matrix and stronger bonding to the particles upon polymerization.

Initially, a cotton plug is carefully placed in the ear canal to serve as a barrier to the inner ear. An impression of the outer ear is taken using a suitable dental impression material. A transparent mold is then made from this impression, using either pourable, unpigmented translucent dental impression material, or a suitable pourable reversible transparent Agar-Agar impression material. This mold is then filled in a filtered light environment with the desired composition of the present invention, covered with a cellophane, mylar or polyethylene film and an opaque metal or plastic disc.
  • This arrangement is then placed in a suitable visible light curing cabinet for 12-15 seconds, or for a sufficient time to allow a polymer shell of approximately one millimeter thickness to form around the exposed surfaces of the liquid. All unpolymerized liquid is allowed to drain out of the mold and the mold is then filled with a suitable air barrier liquid (such as aqueous 1,2,3-propane triol), to prevent air inhibition of the surface. The uncovered mold is returned to the visible light curing cabinet for a full cure of approximately two minutes duration. The air barrier liquid is then poured out of the mold, the mold is rinsed with water to remove any residual traces of air barrier liquid, and a cured shell is pried from the mold, using dry warm air. Thereafter, the shell is trimmed and fitted with a base plate carrying the necessary electronic/acoustical components for the hearing aid, and the two sections are affixed together. The above procedure permits the completion, after one visit, of a custom- fitted hearing aid device.
